As impurities accumulate, the filter automatically slides down and triggers the knocking hammer to rotate, producing a knocking effect, so that the impurities are quickly discharged, greatly improving the efficiency of impurity treatment.

DETAILED DESCRIPTION

[0042] The following is a detailed description of a carton manufacturing wastewater treatment device provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0043] like Figure 1 , Figure 3As shown, an embodiment of the present invention provides a carton manufacturing wastewater treatment device, including an operating table 1, a plurality of self-locking universal wheels 32 are equidistantly installed at the bottom of the operating table 1 to increase the overall flexibility of the equipment, a carton printing device 2 is installed on the operating table 1, and the printing device 2 also includes a printing press cylinder as a core component of the printing machinery, and its surface finish and geometric accuracy have an important influence on the quality of the printed product, an oil-water separator is used to separate ink and water to ensure the purity and stability of the ink during the printing process, a paper pusher is used to push paper during the printing process to ensure the smooth feeding of the paper, and a printing carrier plate 3 is a main supporting surface of the carton paperboard during the printing process. First, the paper pusher smoothly feeds the carton paperboard to be printed under the printing press cylinder, and then the printing press cylinder rotates and contacts the paperboard to transfer the ink evenly and accurately to the paperboard. At the same time, the oil-water separator ensures the purity and stability of the ink. Finally, the printing carrier plate 3 collects the wastewater generated during the printing process and discharges the wastewater to the next step. The specific operating steps are prior art and will not be described in detail here.

[0044] like Figure 1 , Figure 4 As shown, in view of the problem of wastewater collection and treatment generated in the carton printing process, the existing process involves impurity separation and collective treatment, and there are many operating steps and a long time. At the same time, considering the usable impurities such as paper scraps that may be generated in the printing process, the treatment process can be optimized to improve efficiency and resource utilization. Therefore, a separation part for separating the printing ink wastewater remaining on the printing carrier plate 3 is also installed on the inner wall of the operating table 1. The main function of the separation part is to pre-treat the wastewater on the printing carrier plate 3 after printing in the printing step of carton manufacturing. The core is to pre-separate impurities in the wastewater. Through this design, the separation part can ensure that before the wastewater enters a more complex treatment process, the useful impurities therein, such as paper scraps, which have reuse value, are effectively separated from the main body of the wastewater, which not only improves the overall efficiency of wastewater treatment, but also promotes the recycling of resources, reduces treatment costs, and also helps to reduce potential pollution to the environment.

[0045] like Figure 1 , Fig.10As shown, specifically, the separation part includes a separation tank 4, which is fixedly arranged on the inner wall of the operating table 1, and the separation tank 4 is used to store the printing ink wastewater remaining on the printing carrier plate 3. The inner wall of the separation tank 4 is rotatably provided with a first rotating rod 5, and one end of the first rotating rod 5 is rotatably provided with a support plate 222 through a bearing, and a fixed tank 6 is fixedly arranged on the support plate 222. The outer wall of the fixed tank 6 is fixedly provided with a plurality of support rods, and one end of the support rod is fixed to the inner wall of the separation tank 4. The inner wall of the fixed tank 6 is provided with a wear-resistant coating to improve the durability and corrosion resistance of the fixed tank 6 and reduce the friction loss in the wastewater treatment process. The outer wall of the fixed tank 6 is provided with a plurality of separation holes 7, and the inner wall of the fixed tank 6 is rotatably provided with a centrifugal drum 11 1. The first rotating rod 5 passes through the fixed tank 6 and is fixed to the bottom of the centrifugal cylinder 111. The centrifugal force generated by the rotation of the first rotating rod 5 is used to separate impurities in the wastewater. During the centrifugal process, the water in the wastewater can be effectively thrown out, and the impurities in the wastewater can be retained in the centrifugal cylinder 111. The inner wall of the centrifugal cylinder 111 is equidistantly provided with a plurality of through holes 112, and the through holes 112 correspond to the separation holes 7. The inner wall of the fixed tank 6 is rotatably provided with a second rotating rod 8, and the outer side wall of the second rotating rod 8 is fixedly provided with a plurality of guide bars 9. The guide bars 9 are arranged in an arc shape, and the guide bars 9 are gradually enlarged from one end close to the fixed tank 6 toward one end of the cover plate 10, so as to guide the impurities in the wastewater to move along a specific path during the centrifugal process, thereby further improving the separation efficiency.

[0046] like Figure 1 , Fig.10 As shown, a cover plate 10 is fixedly provided on the inner wall of the separation tank 4, and the outer wall of the cover plate 10 is rotatably connected to the inner wall of the centrifugal cylinder 111 through a bearing. A sealing ring is sleeved on the side of the cover plate 10 close to the fixed tank 6 to increase the sealing performance of the cover plate 10 and the fixed tank 6. A rotating disk 11 is fixedly provided on the surface of the centrifugal cylinder 111, and a plurality of tooth blocks 12 are equidistantly provided on the inner wall of the rotating disk 11. A driven gear 13 is fixedly provided on the end of the second rotating rod 8 away from the guide bar 9, and a driving gear 14 is fixedly provided on the outer wall of the first rotating rod 5. The driving gear 14 is meshed with the driven gear 13, and the driving gear 14 is meshed with the tooth block 12. A rotating rod 15 is fixedly provided on the end of the first rotating rod 5 away from the fixed tank 6. A motor 16 is fixedly provided on the inner wall of the operating table 1, and the output end of the motor 16 is fixed to the rotating rod 15. A control panel is provided on the outer wall of the operating table 1, and the control panel is used to control the opening and closing of the motor 16, adjust the speed, and monitor the parameters of the wastewater treatment process.

[0047] like Figure 1 , Figure 8As shown, a collecting box 17 is slidably provided on the inner wall of the operating table 1 at one side of the separation tank 4, and the collecting box 17 is used to collect impurities separated in the fixed tank 6. A drain pipe 18 is fixedly provided on the inner wall of the printing carrier plate 3. A water inlet 19 is provided on the surface of the cover plate 10. The end of the drain pipe 18 away from the printing carrier plate 3 passes through the separation tank 4 and is connected with the water inlet 19. A sewage outlet 20 is provided on the inner wall of the fixed tank 6. A first impurity discharge pipe 21 is fixedly provided on the inner wall of the separation tank 4. The first impurity discharge pipe 21 is connected to the sewage outlet 20, and one end of the first impurity discharge pipe 21 away from the sewage outlet 20 faces the collecting box 17. A impurity discharge hole 113 is provided on the inner wall of the centrifugal cylinder 111, and the impurity discharge hole 113 corresponds to the sewage outlet 20.

[0048] like Figure 1 , Fig.12 As shown, when the wastewater on the printing carrier plate 3 flows into the fixed tank 6 through the first impurity discharge pipe 21, the motor 16 starts and drives the rotating rod 15 to rotate, thereby driving the first rotating rod 5 and the entire centrifugal cylinder 111 to start rotating. This rotation action utilizes the principle of centrifugal force to rotate the wastewater and impurities in the centrifugal cylinder 111 together. In this process, the wastewater smoothly passes through the through hole 112 into the separation hole 7 and flows into the interior of the separation tank 4, while the impurities are retained in the centrifugal cylinder 111 due to the action of centrifugal force, thereby achieving preliminary separation of the wastewater and impurities.

[0049] At the same time, the rotation of the centrifugal cylinder 111 also drives the synchronous rotation of the rotating disk 11, and the tooth block 12 on the rotating disk 11 swings the driving gear 14 accordingly, so that it rotates in the opposite direction of the rotating disk 11. The rotation of the driving gear 14 further drives the driven gear 13 and the second rotating rod 8 to rotate, and the guide bar 9 on the second rotating rod 8 also rotates accordingly. This rotation of the guide bar 9 not only pushes the impurities gathered on the inner wall of the centrifugal cylinder 111 upward along its inner wall, but also continuously contacts with the impurity discharge hole 113 during the rotation process, so that the impurities are squeezed into the sewage outlet 20 and flow into the first impurity discharge pipe 21, so that the impurities entrained by the guide bar 9 are intermittently discharged through the impurity discharge hole 113, and the intermittent discharge of impurities can avoid the blockage of the first impurity discharge pipe 21 caused by the one-time discharge of longer impurities; and the intermittent impurity discharge method can effectively prevent the blockage of the first impurity discharge pipe 21 caused by the continuous and unilateral discharge of longer impurities, and ensure that the impurities can be dispersed and evenly passed through the impurity discharge pipe during the discharge process, thereby greatly reducing the risk of blockage;

[0050] As the guide bar 9 slides upward with the impurities, they will also come into contact with the through hole 112, thereby clearing the blocked through hole 112 and the separation hole 7. In addition, the gradually increasing diameter of the guide bar 9 during the rotation process reduces the gap with the inner wall of the centrifuge barrel 111, which squeezes the impurities carried by the guide bar 9 and further removes the moisture therein.

[0051] like Figure 1 , Fig.10 As shown, in order to further improve the purity of wastewater treatment, a collecting portion is added to the inner wall of the operating table 1, and the collecting portion is specifically used to receive and process wastewater discharged from the separation tank 4 that may still contain fine impurities. This design is intended to ensure that the wastewater after preliminary separation by the centrifugal cylinder 111 can be further purified, and can effectively remove the fine impurities remaining in the wastewater, thereby improving the overall wastewater treatment efficiency and quality.

[0052] like Figure 1 , Fig. 9 As shown, specifically, the collecting part includes a collecting tank 22, which is slidably arranged on the inner wall of the operating table 1 on one side of the separation tank 4. The collecting tank 22 is used to collect the waste water discharged from the separation tank 4. In order to smoothly introduce the waste water discharged from the separation tank 4 into the collecting tank 22, we connect a delivery pipe 23 to the inner wall of the separation tank 4. One end of the delivery pipe 23 faces the collection tank 22, ensuring that the waste water can accurately flow into it. The material of the delivery pipe 23 is selected from corrosion-resistant and wear-resistant materials to ensure that it can withstand the erosion of waste water for a long time without leakage.

[0053] like Fig.13 , Fig.16 As shown, a filter screen 24 is slidingly provided on the inner wall of the collection tank 22, and its main function is to further filter out fine impurities in the wastewater. The inner wall of the filter screen 24 is gradually inclined. In order to improve the filtering efficiency and the discharge effect of impurities, the inner wall surface of the filter screen 24 is designed to be inclined. Specifically, the inner wall surface of the filter screen 24 gradually inclines from the side where the knocking hammer 28 is located to the side where the second row of miscellaneous pipes 30 are located, forming a gradually descending slope.

[0054] like Figure 5 , Fig.16 As shown, a plurality of first springs 25 are fixedly provided at the bottom of the filter screen 24, and the other end of the first spring 25 is fixed to the inner wall of the collection tank 22, a hinge 26 is fixedly provided on the side of the collection tank 22 away from the collection box 17, a rotating shaft 27 is rotatably provided on the inner wall of the hinge 26, a knocking hammer 28 is fixedly provided on the outer wall of the rotating shaft 27, and a buffer layer is provided on the surface of the knocking hammer 28 to effectively reduce the impact and wear on the filter screen 24 during the knocking process, a torsion spring 29 is sleeved on the outer wall of the rotating shaft 27, one end of the torsion spring 29 is fixed to the hinge 26, and the other end of the torsion spring 29 is fixed to the knocking hammer 28, a second row of miscellaneous pipes 30 is fixedly provided on the side of the filter screen 24 close to the filter box, the end of the second row of miscellaneous pipes 30 away from the filter screen 24 faces the collection box 17, and a sliding hole is provided on the outer wall of the collection box 17 for avoiding the second row of miscellaneous pipes 30.

[0055] like Fig.15 , Fig.16As shown, in the design of the filter screen 24, an innovative structure of a limit block 104 and a limit groove 103 is further introduced, aiming to enhance the carrying capacity of the filter screen 24 for impurities and realize effective storage and centralized treatment of impurities. A limit groove 103 is provided on the side of the filter screen 24 away from the second impurity discharge pipe 30, a sliding groove 102 is provided on the inner wall of the collection tank 22, a second spring 101 is fixedly provided on the inner wall of the sliding groove 102, a limit block 104 is fixedly provided on one end of the second spring 101, the limit block 104 is slidably connected to the inner wall of the sliding groove 102, and the limit block 104 is plugged into the limit groove 103.

[0056] like Fig.13 , Fig.16 As shown, when the wastewater in the separation tank 4 flows into the collection tank 22 and is filtered by the filter screen 24, fine impurities will be effectively blocked on the filter screen 24. As the impurities continue to accumulate, their weight gradually increases, forcing the filter screen 24 to slide downward. In this process, the interaction between the limit groove 103 and the limit block 104 begins to appear. When the filter screen 24 slides down, the limit groove 103 squeezes the limit block 104, causing the limit block 104 to compress the second spring 101 and slide into the sliding groove 102. At the same time, the filter screen 24 also squeezes the first spring 25, resulting in further sliding.

[0057] As the filter screen 24 continues to slide down, it drives the second row of impurities 30 to move down together, and presses the rotating shaft 27 to rotate. The rotation of the rotating shaft 27 drives the rotation of the knocking hammer 28. At this time, the torsion spring 29 is compressed. When the knocking hammer 28 contacts the outer wall of the filter screen 24, a knocking effect is generated, so that the impurities accumulated on the filter screen 24 are vibrated and slide along the inclined inner wall of the filter screen 24 to the second row of impurities 30, and finally discharged into the collection box 17. This knocking process not only helps to discharge impurities, but also effectively dredges the blocked filter holes.

[0058] At the same time, the inclined design of the filter screen 24 accelerates the flow of impurities, allowing them to enter the second impurity pipe 30 more quickly, and the expansion and contraction of the first spring 25 causes the filter screen 24 to slide up and down, and this movement further promotes the discharge of impurities. During the up and down sliding process, the knocking hammer 28 will also continuously knock the filter screen 24 to ensure the smooth discharge of impurities.

[0059] When the impurities are discharged through the second impurity discharge pipe 30, the first spring 25 recovers its deformation and pushes the filter 24 to reset upward. At this time, the rotating shaft 27 and the knocking hammer 28 are also reset under the restoring force of the torsion spring 29 and no longer contact the filter 24. When the filter 24 slides upward, it pushes the limit block 104 to move along its outer side wall until the limit block 104 is plugged into the limit groove 103 again, thereby limiting the filter 24. This process prepares the filter 24 for carrying impurities and storing power next time.

[0060] A slide rail 31 is fixedly provided on the inner wall of the operating table 1, and a slide hole is opened on the inner wall of the collection box 17. The collection box 17 is slidably connected to the outer wall of the slide rail 31 through the slide hole. When the collection box 17 needs to be dumped, the collection box 17 can be lifted up by sliding it to dump the impurities.

[0061] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
